Erlang vs Perl: What are the differences?

Erlang: A programming language used to build massively scalable soft real-time systems with requirements on high availability. Some of Erlang's uses are in telecoms, banking, e-commerce, computer telephony and instant messaging. Erlang's runtime system has built-in support for concurrency, distribution and fault tolerance. OTP is set of Erlang libraries and design principles providing middle-ware to develop these systems; Perl: Highly capable, feature-rich programming language with over 26 years of development. Perl is a general-purpose programming language originally developed for text manipulation and now used for a wide range of tasks including system administration, web development, network programming, GUI development, and more.

Erlang and Perl can be primarily classified as "Languages" tools.

"Real time, distributed applications" is the top reason why over 49 developers like Erlang, while over 62 developers mention "Lots of libraries" as the leading cause for choosing Perl.

Erlang and Perl are both open source tools. Erlang with 7.74K GitHub stars and 2.1K forks on GitHub appears to be more popular than Perl with 435 GitHub stars and 152 GitHub forks.

Tilt, DuckDuckGo, and Twilio SendGrid are some of the popular companies that use Perl, whereas Erlang is used by AdRoll, Grooveshark, and Heroku. Perl has a broader approval, being mentioned in 133 company stacks & 64 developers stacks; compared to Erlang, which is listed in 70 company stacks and 47 developer stacks.

    What are some alternatives to Erlang and Perl?
    Elixir
    Elixir leverages the Erlang VM, known for running low-latency, distributed and fault-tolerant systems, while also being successfully used in web development and the embedded software domain.
    Haskell
    Go
    Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.
    Clojure
    Clojure is designed to be a general-purpose language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multithreaded programming. Clojure is a compiled language - it compiles directly to JVM bytecode, yet remains completely dynamic. Clojure is a dialect of Lisp, and shares with Lisp the code-as-data philosophy and a powerful macro system.
    OCaml
    It is an industrial strength programming language supporting functional, imperative and object-oriented styles. It is the technology of choice in companies where a single mistake can cost millions and speed matters,

    The whole backend part (deployment and other scripts, business logic, web interface) is written in Perl.

    Весь бэкенд (скрипты деплоя и прочие, бизнес-логика, веб-интерфейс) написан на Perl.

    I use Perl to rip through log files and compare them to some signature files I have created. When I get a match, it adds the bad guy to the list of shame in MySQL.
